I do love the REPL shell. Sometimes I wonder if this or that would work so with re.pl you can simply evaluate it in an interactive shell just like you can do in interactive Ruby (IRB) or worse, a Basic shell ;-)
Looking at the powers of CatalystX::REPL (integrating REPL into Catalyst to interactively introspect your running app) I must admit that this module was the most helpful one on debugging I found on CPAN in the last months.
The only thing I consider to be strange is it's use of a lot of "black magic" modules, but how could sneaking the symbol table be done else?Martin Gutsch
